Aiwa Cassette Deck Belt Repair?

[lammer]

Hi ive got an aiwa R500 cassette deck (AD-R500) ? and the belts have turned to tar.
I know i've never seen it before.
I need to know whatsize belts are required and or the routing of the belts as I could most likely work out the length if I knew how it routed or the routing if I had the correct belts

belts do turn to goop with age, happens all the time. Obtain the service manual and it will show you the part numbers and position of each belt.
